Sn Areal density as a function of temperature of Sn in the Ni\(_{5}\)(Ge\(_{1-x}\)Sn\(_x\))\(_3\) phase (a, green), the NiGe\(_{1-y}\)Sn\(_y\) phase (b, purple), the surface precipitation (c, red), the germanide-Ge\(_{1-z}\)Sn\(_z\) interface layer (c, teal), and the unreacted Ge\(_{1-z}\)Sn\(_z\) layer (d, gray) obtained by dual-input ANN analysis, together with the analysis uncertainty covering 1 \(\sigma\). The low-temperature domain (filled symbols) and high-temperature domain (open symbols) results are shown.
